33 Claims.

This invention relates to improvements in machines for applying pressure to shoe bottoms and is illustrated herein as embodied in a machine for use in cement-attaching soles to shoes.

An object of the invention is to provide an improved pad box for use in applying pressure to shoe bottoms which may be used with equal facility for operating on various styles and sizes of shoes,'particularly youths and childrens shoes.

In accordance with the foregoing, a feature of the invention comprises an improved pad box structure containing a sole-receiving pad and provided with a mask plate arranged for movement longitudinally of the pad to adapt it vfor operating upon soles of diiferent lengths. As illustrated herein and in accordance with another feature of the invention the mask plate carries a plurality of sole-engaging ngers or feelers which are pivoted on the mask plate and are provided with shoe gages for positioning a shoe relatively to a sole placed by an operator on the pad. The soleengaging feelers are arranged to be moved yieldingly against the edge face of the sole and to be locked in position after they have found the sole, thereby locating the shoe gages properly to p-osition a shoe relatively to the sole. Since the mask plate is movable longitudinally of the pad the feel'ers can, of course, be adjusted properly to accommodate diierent sizes of shoes.

In accordance with still another feature of the invention the sole-engaging ngers or feelers and the Vlocking means are actuated by mechanism mounted on the pad box independently of the' mask plate and arranged to actuate the feelers in any position into which they may be adjusted longitudinally of the pad box. As illustrated, the actuating mechanism comprises an elongated bar supported by toggles and arranged to engage a roll on an arm connecting the actuating mechanism with the feelers. The length of the bar is such that the roll will always be engaged to operate the feelers and the locking mechanism irrespective of the position into which the mask plate and feelers are moved longitudinally of the pad.

Another feature of the invention resides in novel means for pivoting the forward portion or section of the pad box relatively to its central and rear portions about a virtual axis located in a predetermined position substantially at the forward end of the central portion of the pad box and in a plane coinciding substantially with the sole-engaging'surface of the pad. The pivoting means, as illustrated comprises a xed support, a movable support, and mechanism for moving the movable support in a predetermined path while permitting the forward or movable section of the pad box to remain in contact with the xed support.

The above and other objects and features of the invention will now be described with reference to the accompanying drawings and pointed out in the appended claims.

Fig. 5 illustrates a portion of the operating connections for the sole and shoe-positioning gages.

The invention is illustrated herein as embodied in a cement sole-attaching machine of the type disclosed in an application for Letters Patent of the United States Ser. No. 636,202, led October 4, 1932, in the name of Milton H. Ballard et al. Accordingly, the main casting Ill of the pad box is shown in Fig. 1 as secured by screws I2 to a forwardly projecting portion of a shelf or bracket I4 which projects radially of the rotary turret of the machine. VOn this stationary casting I0 are movably mounted a forward casting I6 for supporting the forepart of a fluid-filled pad P carried by the pad box and adapted to receive a sole and shoe, and a second casting I3 slidably mounted on vertical guideways I9 formed on the right-hand portion of the casting I0, as viewed in Fig. l, the second casting I8 being arranged to support the rear or heel-engaging portion of the pad P. The casting I8 is held in positionfon the guideways I9 by a pair of substantially horizontal links- 20, located at opposite sides of the pad box and pivoted at their forward ends to pins 2| mounted in the casting lil and pivoted at their opposite ends to pins 23 carried by the casting I8. A pair of bell crank levers 22, pivoted at opposite sides of the main casting Vlll below the links 20 on a transverse shaft 2li mounted in the side walls of the casting lo, are provided With lower arms which are interconnected by a cross portion 25 (Fig. 2) extending transversely of the casting I8, the portion 25 surrounding a horizontal shaft 26 the opposite ends of which are supported in downwardly projecting ears formed at opposite sides of the casting I8. The interconnected bell crank levers 22 have upwardly extending arms 28 which are connected by heavy springs 30 to a xed shaft 32 supported in the opposite side walls of the stationary casting ID Vand extending through the casting transversely of the pad P, the central or intermediate portion of the shaft 32 being supported by a wall 33 extending upwardly from the base of the casting Il). The springs 3i! act to hold the movable casting I8 in its uppermost positionon the guideways I9, this position being determined by a cam 34 (Fig. 2) carried by a transverse shaft 36 mounted in the casting I8, the cam 34 being arranged to engage a stationary ledge or shelf 38 projecting horizontally from the. upper portion of an upstanding wall 3l which forms one end of the main casting. The shaft v36 is provided withY a hand wheel 40 (Fig. 1) by Vwhich the cam 34 may be rotated into different positions to vary the heightwise position of the casting I8 on the vertical guideways I9 relatively to the main casting Ill, the horizontal links 2D and the bell crank levers 22 forming in effect a parallel motion arrangement whereby the casting I8 is moved in a substantially vertical* direction.

The movable casting I8 is provided with mechanism for positioning the heel ends of a sole'and shoe on the pad, such mechanism being indicated generally in Figs. 1 and 2 by the reference numeral 42 and comprising a pair of soleengaging fingers and a separateY pair of shoeengaging ngers, each pair being mounted for equal and opposite pivotal movement independently of the other pair laterally ofthe pad. This heel-end positioningy mechanism is not claimed herein since it is not of our invention. It is, however, fully disclosed and claimed in Letters Patent of the United States No. 2,005,754, granted June 25, 1985, on an application filed in the name of Robert Sandberg. The casting I8 is also provided with means for varying theY heightwise position of the heel portion of the pad P in accordance with the height of heel which is to be attached to the shoe, suchmeans including a pair of plates, indicated by the reference numeral 43 in Fig. 2, which are movable longitudinally of the casting I8 and are arranged to enter a recess in the heel end of the pad when the ,casting I8 is adjusted heightwise-relatively to the main Acasting by means of the cam 34. Since this mechanism likewise forms no part of our invention it is not claimed herein but is fully disclosed and claimed in an application for Letters Patent of the United States, Serial No. 722,537, led April 26, 1934, in the name of Frank Kennison.

The casting I6, which supports the forepart of the pad P, is connected to the main casting I8 in such a manner that, in order to adjust the forepart of the pad into a proper angle for the spring of the last in the shoe being operated upon, the

casting I 6 is moved about a virtual axis located substantially in the plane of the upper or soleengaging surface of the pad P, this axis lying also in a vertical plane located substantially `at the forward end of the pad engaging portion of the main or fixed casting I0. In order to accomplish this pivoting movement the casting I6 is` provided at opposite sides of its lower wall with a pair of downwardly projecting lugs 44 having slots 46 formed therein which engage the fixed shaft 32 and thus support the end of the casting i3 adjacent to the stationary casting IU. Another shaft 48, mounted in downwardly projecting ears or lugs formed on the lower side of the casting I 6, is engaged inwardly of the lugs by ears 55 projecting upwardly from an adjustable supporting member 52 extending transversely of the pad box between the opposite side walls of the casting I5. The member 52 has a hole threaded internally to receive left-hand threads on the shank portion of aspiral gear 54 which, in turn, is provided with a right-hand threaded opening to receive the threaded portion of a stud 55 pivotally mounted on a short pin 58 extending transversely between ears 5U formed at the central portion of the base of the casting Ill. The threads on the shank portion of the gear 54 are left-'hand threads while those on the stud 56 are right-hand so that rotation of the gear in a counterclockwise direction, as seen in plan view, will cause the gear to move upwardly on the righthand threads of the stud as the supporting member 52 moves upwardly on the left-hand threads of the shank of the gear 54. By this construction the movement of the supporting member 52 for veach revolution of the gear 54 will be substantially increased. The spiral gear 54 is rotated by means of a worm gear 62 secured to a horizontal shaft E4 mounted in bearings in opposite sides of the casting I9, the shaft 64 projecting forwardly toward the operator, as viewed in Fig. 1, and being provided with a handle 66 by which it may be rotated.

The shaft 48 projects beyond its bearings in the ears on the casting l5 and is flattened at its opposite ends, as shown in Fig. 1, to engage inclined slots 68 formed in the opposite side walls of the xed casting Ill, these slots being inclined at an angle of approximately to the horizontal. As the gear 54 is rotated by the worm 62, for example, in a counterclockwise direction, as seen in plan View, the shaft 48 is elevated swiftly in the inclined slots 58 thereby rotating the casting I 5 about the fixed shaft 32 and also moving it transversely of the shaft, the slots 46 permitting the casting I6 to move longitudinally of the pad relatively to the shaft 32 without losing contact therewith. The location of the shaft 32 and the direction of the inclined slots 68 are such that the casting I5 will be caused to rotate about a virtual axis or pivot which is located substantially in the plane of the sole-engaging surface of the pad and in a vertical plane separating the fixed casting I0 from the movable casting I6, this plane coinciding Vsubstantially with the forward end of the shank portion of the pad. Since the casting I6 moves longitudinally of the casting I0 when it is adjusted int-o different angular positions relatively thereto to cause the upper surface of the pad to conform more closely to the longitudinal contour vof the shoe bottom, a thin plate lil is secured to that surface of the casting I5 which engages the lower wall of the pad and is arranged to overhang the inner edge of the casting thus covering the space separating the casting I6 from the casting Ill and preventing the lower wall of the pad from bulging out when pressure is applied to a shoe and sole mounted thereon. The openings between the side walls of the two castings are likewise covered by a pair of thin plates 'II secured by screws to the upper portions of the opposite side walls of the stationary casting I0, as shown in Fig. 1. The sur- Cil face of the casting I6 which engagesthe lower wall of the pad is also provided with an opening 12 through which the pad may be filled with uid, for example,v water, any usual clamp and plug arrangement being utilized to seal the opening in the pad and thus prevent leakage, this being illustrated herein as a clamping bushing 'i4 having a threaded shank on which is mounted a clamping nut i5 and being provided also with an internal opening into which is `threaded a plug 76. v

The left-hand portion of the casting I6, as viewed in Figs. l and 2, extends upwardly relatively to the right-hand portion and has mounted on the upper surface of this raised portion a flat plate 'i8 secured in position by screws il@ and extending along each side Wall of the casting |6 longitudinally of the pad box for the full length of the casting. The inner periphery 8| of the plate 'It (Fig. 3) conforms substantially to the shape of the forepart of a sole except that it is much larger than avsole and this peripheral portion projects beyond the adjacent edge of the casting i6 and ts into a recess 'llformed in thei upper edge of the forepart of the pad P so that the plate 'i8 will hold the pad in position in the movable casting it. The opposite lateral edges of the plate i8 project beyond the side walls of the casting i6 and serve as tongues upon which is slidably mounted a mask plate 32 somewhat greater in width than the casting le and having an inner periphery 84 which also conforms substantially to the outline of the toe end of a so-le. The mask plate 82 is moved alongthe tongues provided by the plate 'i8 by a pair of small gears or pinions 86 and 8l secured respectively to the opposite ends of a horizontal shaft 88 rotatablyy plate into diiferent positions longitudinally of the pad box.

In order to maintain the mask plate 82 in anyA position into which it may be adjusted longitudinally of the casting it, there is secured to the forward sidewall of this casting, as viewed in Fig. 1, a small plate Sii provided with a tooth which normally engages the teeth of the pinion 86, thus preventing the latterv from being rotated. A compression spring 96 (Fig. 3) is provided at the opposite end of the shaft 38, one` end of the spring being seated in a recess formed.

in the side wall of the casting it and the other end bearing against the vinner surface of the pinion 8l, the spring acting to maintain the shaft 88 at its innermost position relatively .toi

the casting i6, this position being determined by the inner face of the forward pinion 85 bearing against the casting it. When it is desired to move the mask plate into a different position longitudinally of the pad box, the operator pulls the shaft 88 forwardly against the action of the spring 9&3 by the handle thereby disengaging the pinion 86 from the tooth on thexed plate 94. The shaft is then rotated to move the mask plate into the desired position longitudinally of the pad box. Upon release of the handle the spring 96 moves the shaft 36 automatically back into its original position to cause the tooth on the plate 94 to engage the teeth of the pinion fit and thus hold the mask platein Vits adjusted position. The longitudinal movement of the mask kplate 32 rearwardly or .away from the stationary casting lil is limited by means of a downwardly projecting nger 98 (Fig. 1) secured by a screw to a forward portion of the mask plate and arranged to engage a horizontal pin itil carried bythe plate 94 and projecting into the path of the finger 98. Movement of the mask plate in the opposite direction is limited by engagement of its forward edge with the upper portions of the v'oppositeside walls of the stationary casting.|l.f i

1 The mask plate 82 carries a bracket |02 which is secured byscrews |04 to the left-hand portion of its upper surface as viewed in Figs. land 2. The width ofthe bracket |02 is somewhat less than the width of the mask plate and the bracket is provided at itsV inner portion with two outwardly'diverging arms |36, |08 (Fig: 3) which, at their outer ends, carry vvertical pins Ht, M2, which form, :.respectively, Vfixed pivots about which a pair of curved arms H4 and M6 ro-tate, each arm being provided with a sole-engaging iingerJor feeleras will presently be described. The arms |4 and H6 are arranged in crossed relation to'each other as shown in Fig. 3 and are operated 'yieldingly to engage the edge face of a sole'at opposite sides substantially at the tip line thereby nding'the sole and being position-ed thereby. The arms are not. mounted directly on thepins i8; H2, since they are also arranged to-rotate in a direction at right angles toy their pivotal movement about these pins on a pair of horizontal pins 8 and I2!! carried respectively in theouter ends ofk two inwardly extending llevers |22 land |24, fulcrumed .directly on the vertical pins Ii and ||2 and forming'in effect inner arms for the curved arms i4, ili. The curved arms H4, ||6 pivotfreely about the horizontalpins H8, inthe levers R22, |24 and are thus permitted to rest by their own weight on the sole-engaging surface of the pad as they are moved toward or away from theedge face of the sole by pivotal movement of the levers l2?, |2 about the vertical pins Htl, H2. The levers |22, |24 extend inwardly toward the center ofthe mask plate and at their inner ends are considerably wider than at their outer ends and areY provided, respectively, with arcuate slots E26, |23, theV arcs of which are struck from centers coinciding withlthe centers of the vertical pins im, ||2. The widened portions of the levers 522, U24 overlap eachother so that the arcuate slots E26, |28 cross, as shown in Fig. 3.

Some distance inwardly of its opposite sides the bracket||l2 is provided with upwardly projecting walls |3, |32 (Figs. 1 and 3) the upper ends of which support a horizontal shaft l34 extending transversely or widthwise of the pad box, as shown in Fig. 1.y Between the walls i |32 the upper surface of the bracket |82 is provided with a groove |35` extending longitudinally of the pad box and located substantially on its longitudinal median line. In the groove |36 is se` cured a tongue |38 which projects upwardly a short distance Aabove the groove, as shown in Fig. 2, and serves as a guideway for a slide plate Mii the lower surface of which is provided with a similar groove |42 tting ,the tongue |38. At the left-hand end of the slide plate Mt, as viewed in-Figs. 2 and 3, is mounted a transverse pin |44 whichrprojects beyond each side of the plate and serves as a pivot for a U-shaped arm |46 which extends forwardlyV under the curved armsl I4,` |.|6 and the inwardly extending levers |22, |24, and s provided with 'an abutment to be later described for engaging the toe end of a sole which is placed on the pad by the operator, the arm |46 being loosely pivoted on the pin |44 and resting by gravity on the surface of the pad. As shown in Fig. 2, the slide plate |40 underlies and supports the slotted portions of the levers |22, |24 and is provided with an elongated slot |50 a portion of which registers with the arcuate slots |26, |28 in the overlapping portions of the levers. An upstanding pin |52, carried loosely in a hole in the bracket |02, extends upwardly through a hole in the tongue |38 and through the slot |50 and the arcuate slots |26, |28 in the overlapping levers |22, |24, the pin |52 being provided at its upper end with an enlarged portion |54 which enters a recess in the forward end of a substantially horizontal arm |56 pivoted on a xed shaft |58 secured by set screws in the upwardly extending side walls |30, |32 formed on the bracket |02. A screw |60 extends into the recess in the arm |56 and engages the enlarged end of the pin |52 thus providing an adjustable 'stop for determining the distance Whichthe pin can enter the recess.

It will be noted in Fig. 2 that the recess in the arm |56 is located a short distance to the right of the center of the shaft |58 so that as the arm is rotated in a clockwise direction about the shaft |58 the pin |52 will be forced downwardly in the bracket |02 with considerable force. Interposed between the enlarged end of the pin |52 and the slotted portion of the overlapping lever |24 is a washer |62 which, when the arm |56 is rotated in a clockwise direction, is forced downwardly against the lever |24 to clamp this lever, the lever |22, and the slide plate |40, upon which the central arm |46 is mounted, against the bracket |02, thus locking the plate and the arms in the positions they occupy at the time the member |56 isrotated. Opposite movement of the arm |56 will, of course, release the pressure on the pin |52 and unlock the overlapping levers and the slide plate thereby permitting the opposite arms ||4, ||6 to be moved about their vertical pivots and the central arm |46 to be moved longitudinally of the mask plate by sliding movement of the plate |40 along the tongue |38.

The arms ||4 and ||6 are normally urged inwardly about the Vertical pivots ||0, ||2 toward a sole on the pad by means of a tension spring |64 connected at its opposite ends to upstanding pins |66, |68 mounted respectively in the levers |22, |24 some distance outwardly or to the left, as viewed in Fig. 3 of the pivot pins ||0, ||2. The central arm |46 on the slide plate |40 is urged inwardly toward the sole by a torsion spring |10 (Figs. 1 and 3), one end of which is inserted in a recess formed in an outwardly projecting portion |1| of the bracket |02 and the other end in a hole in the end of the plate |40.

In order to release the locking mechanism and move the arms away from the sole against the action of the springs |64. and |10, there is provided mechanism carried by the mask plate and capable of being operated in any position into which the mask plate may be moved longitudinally of the casting I6. This mechanism is, in turn, operated by further mechanism carried by a fixed bracket secured to the side of the casting I6 remote from the operator, as viewed in Fig. 1, and connected to mechanism forming a part of the sole-attaching machine referred to above, the latter mechanism being operated, by a treadle on such machine. This mechanism for operating the arms will now be described.

The opposite ends of the horizontal shaft |34 (Fig. l) project laterally beyond the upstanding walls |30, |32 and have pivotally mounted thereon a U-shaped lever |12 the bar portion of which is located between the upstanding walls. The lever |12 is provided with a pair of downwardly extending arms |14, |16 located outside the walls |30, |32 and carrying respectively at their lower ends horizontal pins |18, |80. The pins |18 and project inwardly of the arms as viewed in Fig. 3 and are loosely engaged by the outer ends of a pair of substantially horizontal links |82, |84, these links having elongated slots |86, |88 formed at their opposite ends which respectively engage upstanding pins |90, |92 mounted on inner portions of the inwardly extending levers |22, |24 which carry the arms ||4, ||6.

The central or bar portion of the U-shaped lever |12 has a cam surface |64 (Fig. 2) formed thereon which is located directly above the piv-V oted arm 56 and is arranged to engage a roll |96 mounted on a horizontal pin |98 extending transversely through a slot 200 formed in the central portion of the arm |56. The other extremity of the arm |56, as viewed in Figs. 1 and 2, is provided with an adjustable screw 202 which eX- tends through the arm |56 at right angles thereto and has a. small projection formed on its lower spring 204 tends normally to force the arm |56 in a clockwise direction about its pivot |58 to press the screw |60 against the head of the pin |52, thus forcing the pin downwardly in the bracket |02 and clamping the washer |62 against the overlapping portions of the levers |22, |24 and the slide plate |40, thereby locking the various arms against further movement. When the U-shaped lever |12 is rotated in a clockwise direction, as viewed in Fig. 2, the cam surface |94 engages the roll |96 and forces the arm |56 in a counterclockwise direction about the pivot |58, thereby compressing the spring 204 and raising the forward end of the arm to release the pressure of the screw |66 on the pin |52 and thus unlock the levers |22, |24 and the slide plate |46. t

Further clockwise movement of the lever |12 swings the depending arms |14, |16 toward the left thereby moving the links |82, |84 in the same direction to take up the lost motion provided by the elongated slots |86 and |88 in these links so that the ends of the slots will engage the upstanding pins |90, |92 in the levers |22, |24. These levers are thereupon rotated about the pivots ||0, ||2 toward the left as viewed in Fig. 3 against the action of the spring |64, thereby positively retracting the opposite arms 4 and |6 from the edge face of the sole.

The horizontal link |84 is provided about midway of its length with a laterally projecting pin 208 (Fig. 3) which is arranged to engage an upstanding pin 2|0 carried by a forwardly extending arm 2|2 pivoted on a pin 2|4 mounted in the mask plate 82. Engagement of the pin 208 with the upstanding pin 2|0 rotates the arm 2|2 about the pivot 2|4 in a clockwise direction as viewed in Fig. 3. The forward end of the arm 2|2 is reduced in size and is arranged to engage a small vertical pin 2|6 carried by a lug 2 i8 projecting laterally from the rear side of the slide plate |40, the lug 2|8 being located above the 75 U-shaped arm 126 pivoted to this slide. By this arrangement as the arms 114, 118 are withdrawn by movement of the links 182, 184, the slide plate 148 and the central arm 1418 are retracted along the tongue 13S. The lost motion provided by the slots in the horizontal links 182, 184 is approximately equal to the distance separating the pin 288 from the vertical pin 218 so that after this lost motion has been taken up and the arms 1 14, 1 16 begin to move away from the sole, the central finger 1215 will also be moved rearwardly or away from the sole against the action of the torsion spring 1111.

Rotation of the U shaped lever 112 about the shaft 13d is accomplished by the following mechanism. On the further side of the lever 1'12, as viewed in Fig. l, is provided a substantially horizontal arm 228 (Fig. 3) which extends to the left and is provided at its outer end with a roll 222 arranged to engage the upper surface of an elongated bar 224, the roll being held against the bar by a tension spring 226 the upper end of which is connected to the arm 226 by a pin 228 and the lower end to the movable casting 16. The bar 2211 extends longitudinally of the pad box for a distance somewhat greater than the length of the mask plate 82 and is supported by means of two pairs of toggles 238, 232 (Fig. 4), the lower links of which are pivotally mounted on fixed pins 234, 235 carried in lugs 238, 248 projecting laterally from the farther side wall of the casting 16. The bar 2241 is connected to the upper links of the toggles 238, 232 by pins 231, 233 which extend beyond the inner sides o-f the links for some distance and carry rolls 266 and 262, the purpose of which will presently be explained. The lugs 238 and 248 on the casting 18` are elongated, as shown in Fig. 4, and have mounted on the portions thereof opposite the pins 231i, 236 a bracket 242 which is secured to the lugs by means of screws 2M and 246, and a third screw 248 mounted in a downwardly extending arm 228 of the lug 238 and arranged to fasten a lower arm 258 of the bracket 242 to the lug 238, thereby strengthening the mounting of the bracket on the casting. The upper side of the bracket 26.12 is provided at its opposite ends with two upwardly projecting portions 252, 254 provided respectively with elongated slots 256, 258 which extend substantially at right angles to the upper surface of the mask plate 82. The rolls 262, 262 previously referred to as being mounted on the toggle pins 281, 233 are arranged to enter the slots 256, 258 and thus control the direction of the movement of the upper ends of the toggle links and also of the elongated bar 228. The links of each pair of toggles 238, 232 are connected together by pins 284, 266 and another link 288 extends between these pins substantially parallel to the bar 224 to connect the centers of each pair of toggles so that the toggles will be operated simultaneously. The inner or righthand end of the connecting link 2158 as viewed in Fig. 4 extends beyond the pin 268 and-is connected to a short intermediate link 218 which, in turn, is pivotally connected to the upper end of an upwardly projecting arm. of a bell crank lever 212, the latter forming a part of the operating mechanism of the cement sole-attaching machine disclosed in the Ballard application Serial No.` 636,202 mentioned above.

Before proceeding to describe in detail the mechanism which actuates the toggles 238, 232 it should be explained that thesole-engaging members or arms 112 and 11e` are provided respectively on their -outer ends with sole-engaging fingers or feelers A212, 216, sometimes referred to hereinafter as sole nders, and that the central U shaped arm 1116 is likewise provided with a sole-engaging feeler or finder 218 as shown in Figs. 2 and 3. Each of these fingers or feelers carries a shoe gage mounted in superposed relation thereto, the shoe gages being indicated, respectively, in- Fig. 3 by ,the reference numerals 2138, 282 and 28d. The shoe gages are slidably mount-ed on the sole feelers and are arranged for adjustment relatively thereto through the rotation of manually operated frusto-conical members mounted on the feelers and provided with pins located eccentrically with respect to centers of the said members and entering transverse slots in the shank portions of the shoe' gages whereby the latter may be mo-ved in guideways formed inthe upper surfaces of the sole-engaging feelers, this mechanism being fully shown and described in the above-mentioned Ballard application, Serial No. 636,202. This constructionis to permit adjustment of the shoe gages relatively to the feelers or finders to accommo` date shoes the soles of which may extend beyond the shoe upper different amounts, as is common in some styles of shoes..

The machine in the application referred to is also provided with a forwardly and rearwardly swinging frame member 298 (Fig. 1) which carriesy suitable abutments 292 and 29d for engaging the shoeand last and forcing the shoe andysole downwardly against the upper face of the pad to ap-ply the sole-attaching pressure, a handle 268 being provided whereby the swinging frame may be moved forwardly by the operator into operative position over the shoe. Since this mechanism forms no part of the present invention it is not described in detail herein and refer.

ence may be had to the Ballard application mentioned above for a full disclosure thereof.

Returning now to the mechanism for operating the two pairs of toggles 238, 232, the upper arm of the bellcrank lever 212 (Figs. 4 and 5) is moved to the left to straighten the toggles, elevate the bar 224, and, through the arm 220, to rotate theV U-shaped lever 112, thereby moving the horizontal links 182, 184 away from the sole and by means of the connections already described, positively withdrawing the opposite soleengaging feelers 2111, 216 and the central feeler 218 with their corresponding shoe gages away from the sole and shoe. The bell crank lever 212 is fulcrurned at 298 to a suitable part of the rotating turret of the machine as disclosed in the Ballard application previously referred to. A tension spring 388 anchored at 302 to the upstanding arm of the bell crank lever 2'12 and at 384 to the frame of the machine urges the bell crank lever in a clockwise direction as viewed in Fig. 5 until an adjustable stop 386 carried by the lever 212 engages a stationary abutment 308, the spring 388 tending normally to break the toggles and to permit the various sole-engaging members to be urged inwardly toward the edge face of the sole by the springs 164 and 110.

A rod 318 extends upwardly from a treadle 312 of the machine forwardly of the fulcrum of the treadle and is pivoted at 314 to a lever 316 which is fulcrumed at 318 to a stationary cam track 328 adjacent to the operating station of the machine and in close proximity to the path of movement of an approximately horizontal arm 322 of the bell crank lever 212 as the pad box moves into and away from the operating station. A roll 324 carried by the arm 322 rides along the cam track 320 as the pad box approaches the operating station and rocks the lever 212 in a counterclockwise direction, as viewed in Figs. 4 and 5, thereby moving the horizontal link 268, which connects the toggles 230, 232, toward the left, thus straightening the toggles. This action causes the roll 222 on the arm 220 to be elevated by the bar 224 to retract the feelers and their shoe gages from the sole and shoe.

A movable cam track section 326 carried by the lever 316 forms a continuation of the cam track 326 and is so positioned that the turret of the machine comes to rest with the roll 324 on the lower arm of the bell crank lever 212 upon the cam track section 326. With the parts in this position the bell crank lever 212 has been rocked in .a counterclockwise direction from the position shown in Fig. 5 so that the toggles have been straightened to withdraw the feelers and gages from the sole and shoe. After the shoe previously operated upon has been removed and another sole has been placed upon the pad with its forepart in position to be engaged by the various feelers the operator iepresses the treadle 312 thereby moving the cam track section 326 downwardly. This permits the bell crank lever 212 to move in a clockwise direction into the position shown in Fig. 5 under the action of the tension spring 3110, thereby moving the connecting link 268 to the right, asviewed in Fig. 4, to break the toggles 230, 232, lower the elongated bar 224, and permit the sole-engaging feelers to move inwardly yieldingly to nd the edge face of the sole under the action of their springs 164 and 110.

In order thatit will not be necessary `for the operator to hold his foot on the treadle 312 a latch lever 328 is fulcrumed at 330 to the cam track 320. The latch lever 328 is provided with a shoulder 332 adapted to engage a hardened steel plate 334 secured to the lever 316 and the latch lever is urged in a counterclockwise direction as viewed in Fig. 5 by a tension spring 336. When the treadle 312 is depressed the latch lever 328Y is moved by the spring 336 until its shoulder 332 snaps past the end of the hardened plate 334, thereby latching the lever 316 in the lowered position shown in Fig. 5. The operator may now remove his foot from the treadle 312.

After the forepart of a sole has been found and engaged by the feelers 214, 216, and 218 and the forepart of a shoe has been inserted between the shoe gages which are now locked in position so that they will locate the shoe relatively to the sole, and after the last and shoe-engaging abutments 292 and 294 of the machine have been moved downwardly into engagement with the last and shoe to apply the sole-attaching pressure to the shoe and sole, the turret-rotating mechanism of the machine is operated in the manner disclosed in the Ballar-dV application Ser. No'. 636,202 and the bell crank lever 212 is moved bodily to the right as viewed in Fig. 5. In order to release the latch 332 and permit the lever316 to rise, a cam roll 338 is carried by the bell crank lever 212, the axis of the roll coinciding with the axis about'whioh the bell crank lever 212 is fulcrumed. As the roll 338 moves to the right it rst engages the upper side of the lever 316 and then engages an upwardly extending cam surface340 formed on'a finger extending to the right from the latch lever 32,8, thereby rocking this lever in a clockwise direction against the tension of the spring 336 and, since the roll 338 has by this time passed out of engagement with the lever 316, permitting the latter to rise.

As illustrated, the lower end of the rod 313 is surrounded by a compression spring 342 bearing at its upper end against an abutment 344 adof the treadle and at its upper end to a hook 343 threaded into a lug on a stationary portion of the frame of the machine. The latching mechanism is so constructed, however, as to permit the rod 3111 to be forced downwardly by the roll 324 against the compression of the spring 342 which is lighter than the treadle spring 346. It will be noted that the toggles 23B, 232 may be straightened or broken by the mechanism just described to move the bar 224 upwardly or downwardly irrespectively of the position longitudinally of the H pad box into which the mask plate 82 and the mechanism carried thereby are moved. Moreover, the length and position of the bar 2215 are such that the U shaped lever 112 will be rotated by the bar to operate the sole and shoe-engaging f mechanism in any position into which the mask plate 82 may be moved. Consequently, the mask plate may be adjusted toward the right, as viewed in Fig. 2, to accommodate a small shoe such, for

example, as an infants or a childs shoe, or it f may be adjusted toward the left to accommodate larger shoes, such as youths or misses shoes, without affecting the operation of the sole and shoe-positioning mechanism in the least.

As illustrated'in Figs. l and 2, the pad box is provided with Vmeans which has an eiect similar to that which would be produced by adding uid to the pad when a small shoe is to be operated upon and by removing fluid from the pad when a large shoe is to be operated upon, thereby changing the contour of the upper or sole-engaging surface of the pad to accommodate different sizes of shoes. This means comprises a movable plate 350 pivoted on the shaft 32 and having an extension 352 pivotally mounted on its rear or rightf hand end, the extension being arranged to enter a recess or'groove 354 in the upper end of the upstanding wall 31 so that the members 350 and 352 form, in effect, a hinged plate or door for supporting the lower wall of the pad substantially under the shank portion of the shoe. The hinged plate 3511 is moved about its pivot 32 by a polygonal cam 353 mounted on a transverse shaft 358 which is provided with a hand wheel 360 (Fig. 1) by which the cam may be rotated to move the plate and the lower wall of the pad toward or away from the sole-engaging wall of the pad, thereby changing the contour of the soleengaging surface of the pad to adapt it for the size of shoe which is to be operate-d upon. The above mechanism forms no part of the present invention and accordingly is not described in further detail herein. It is, however, fully described and claimed in an application for Letters Patent of the United States Ser. No. 722,537, led April 26, 1934, inthe name of Frank Kennison.
